The PERT Estimation Standard
Developed to combat the 'Planning Fallacy', the PERT formula weights the Most Likely scenario 4x heavier than the extremes.

?What is PERT?
Project Evaluation and Review Technique (PERT) is a statistical tool used in project management to analyze the tasks involved in completing a project.
?Why the 4x weight on 'Likely'?
The PERT formula uses a weighted average (Beta Distribution) to account for the fact that the most likely scenario is statistically much more probable than the extremes.
?What does Schedule Variance mean?
It represents the level of uncertainty in your timeline. A higher variance means your project is more susceptible to delays.
